"Locker-room mathematics" for parameter counts is a fair description of how model selection often sounds.

The practical argument against size-first is that for most production tasks the model is not the bottleneck. In anything retrieval-shaped, a 7B with the right passage in context beats a 405B with the wrong one, and the gap is not close. Parameter count buys you capability on the hard tail; it does nothing for the far more common failure where the evidence never arrived.

The other cost worth naming is that bigger models make everything slower to iterate on, so you run fewer experiments per week. That compounds against you far faster than a few benchmark points compound for you.

Exactly. Retrieval quality and iteration speed are often more important than raw parameter count.

Iteration speed is useful only if the experiments isolate a cause. For the retrieval example, I would first give both model sizes the same known-answer passage, then run them on the same retrieved context. That separates the model's ability to use evidence from the pipeline's ability to find it.

It also avoids overstating my earlier 7B-versus-405B comparison: correct context is a major advantage, but it does not guarantee that every smaller model can interpret the passage correctly. The two controlled runs would show which part actually deserves the next engineering effort.
